RING TRAVELER.

To all whom it may concern:

Be it known that I, PHILIP C. \VENT WORTH, a citizen of the United States, residin at Providence, county of Providence, State of Rhode Island, hzwe invented certain new and useful Improvements in Ring Travelers, of which the following is a specification.

This invention relates to ring travelers, and has for its object to provide a ring traveler which will materially reduce the percentage of thread cuts and will lessen the tendency of the traveler to become loaded with lint. I

The constant chafing or scraping action of the thread on the flat, thin, bowportion of the usual ring traveler not only frees the fibres of the thread, causing the traveler to become loaded with lint, but eventually severe the thread itself.

To the end therefore of overcoming these several objections, I have devised my present invention. In it the bow portion of the traveler is concavo-convex in form with the convexity disposed towards the ring, providing a smooth, rounded surface past which the thread may freely draw with the minimum friction, thus materially reducing both the tendency of the thread to sever and the tendency of the traveler to become loaded with lint.

As illustrative of the principles of my invention, I shall describe and show a ring traveler which not only has been found satisfactory in use under actual working conditions, but in itself is a form well adapted to the requirements of manufacture. The' construction and operation of such traveler is described and illustrated in the accompanying specification and drawings, throughout which like reference characters are correspondingly employed, and characteristic features of novelty are particularly pointed out in the appended claims.

In the drawings:

eler on the line 3.3, Fig. .2.

Serial No.' 501,510.

Fig. 1 is a plan view of a ring traveler in accordance with my invention.

F g. 2 is a side elevation thereof, and

F1g53 1s a cross-section through the trav- Fig. 4 is a perspective view showing the traveler in position upon a spinning ring.

I have indicated at 1 the horns and at 2 the connecting bow or circle portion of a ring traveler of standard type, at 3 a spinning ring and at T a thread. If desired, the traveler may have a ventilating slot S' in its bow portion 2.

My invention consists in making the bow portion 2 of the traveler concavo-convex in form with the convexity disposed towards the ring. as indicated at 4, Fig. 3, whereby a smooth, rounded surface is presented to the thread. Such surface offers the minimum of friction to the thread, thereby reducing the loading tendency of the traveler and to a considerable degree avoiding cutting of the thread.

Various modifications in the form and construction of my device may obviously be resorted to if within the limits of the appended claims.

What I therefore claim and desire to secure by Letters Patent is;'

1. A ring traveler having a concavo-convex bow portion with the convexity disposed towards the ring.

2. A ring traveler of flat sheet material having a concavo-convex bow portion with the convexity disposed towards the ring.

3. A ring traveler having a concavo-convex bow portion with the convexity disposed towards the ring and having an opening through said bow portion.

In testimony whereof I afiix my signature in presence of two witnesses. PHILIP C. WENTWORTH.
